Abstract

Several case reports described acute and subacute decompensations that were reversed after percutaneous interatrial septal defect (ASD) closure. At least 30% of patients post MitraClip will continue to have a persistent ASD at 1 year. Few retrospective studies described various echocardiographic associations with persistent ASD but there is no conclusive evidence that it is the cause of a poor outcome. Conclusion: At this time routine closure of ASD post MitraClip is not recommended unless there is hemodynamic decompensation that cannot be explained by other factors.

Keywords: Atrial septal defect; Atrial septal defect closure; Interatrial septal defect; Interatrial septal defect closure; MitraClip.
